I used an audio scrubbing technique for DXARTS 460 that created some
very interesting sonic textures. In short, I used Spark LE (or Digital
Performer) to scrub audio back and forth and recorded the output to DAT.
I then chose from among the most interesting textures, sometimes applying
additional effects, for audio composition. The technique is much more
flexible than using CSound, for instance. I'd like to use this technique
once again (but am unable to do so at home) to generate a substantial
amount of material for a larger, more complete
composition.
